Referring to the accompanying drawings, `which `are madea part hereof and on which similar'reference characters indicate similar parts,

j Figure` 3 *isy a section on and e y gure 4 is a side elevation of amodiiied form ofthechair e l In the drawings referencecharacter I indi- Vune 3 3 er Figure 2 cates the' front legsof the chair positioned paral- `lel to each` other andconnected by parallel rods II and I2 near the bottom and mid points, re-

spectively. The ro'ds`are rigidly fixed in any suit'- ablemanner tothe legs I0. The rear'legs I3'are pivotedj tothe upper ends of the legs I0 by bolts l or pins I4 and extend rearwardly anddownward-` .lyjbeing connected by a rod `I5 xed to each ad-f jacent their lower ends. Armrests'rII pivotally connected on the pins I4 at htheir front ends extend rearwardly and are pivotallygconnected `by bolts or pins I1 at their' rear ends tothe rdownwardly extending brace members I8."

. Diagonal brace members I9 Aare pivotally conneared at tneirupper' ends on the rod |2 with the y tioned adjacent the innersurface of the legs upper portion thereof `mojecting beyond the frofitllegsV II'IL` rThe members I9 'extend rearwardly4 anddownwardly where'they are pivotallyconnected to the lower ends of brace 'members I8 -by a rod 20. The rod is adapted to seat in the notches 2I Aformed in the upper edge of the. rear legs to hold the `frame work imposition, as shown in Figure` 2. The brace membersl I9 `are posiand thefbrace'members I8` areadjacent the inner surfaces of the brace members I9. The arm restsv are positioned against the outsidel surfaces of the rear leg's'and the brace members I8. 'I'his arrangement permits'the` framework tobe folded l'when the rod 20 is lifted out `of the notches 2|.

The back is formed of .side members 22 piy.- oted near their centers on the pins I'Izadjacent the inner surfaces of the brace members I8 and folded into a verycompact condition when lnot y, shown in Figure `2; l

. shown in Figure 2 are pivotally :connected to the side rails by bolts or pins 26 at a point spaced from the extremerear ends of theside rails 24 10 for a purpose .which will be later described. In the modified form shown in Figure4 the lower endsof the sidev members 22 are plvotally mounted on the rear seat rod 25 instead of at Athe `points 'I'he seat is provided with 'a bottom form of sev-- eral layers of suitable flexible material, preferablyY canvas,fone layer 21 is stretched and secured to the' side rails and the other 1ayer`28 is stretchedv and secured to the rodsv25. Strips 29` of suitable zo material are fixed to the underside ofv the side rails onthe material forming the seat; bottom to prevent unduewear at this point due to sliding of the side rails on the .upper ends of the brace members Iii.` The strips` 29 project outwardly 25 along 4the side rails to prevent contact of the seat material with the innersurfaces of the legs I0 as shown in Figure 3, to eliminate -undue wear along this surface. l s

The back is provided with a strip 30 of suit-k 30 able material secured at one end to the rod '23 and secured at the other end to the rear rod 25 of Y the seat. The strip 30 at itslower end extends` i around `the back of and under. the rod 25 with the strip 28 ofthe seat extending over thetop 85 l ofthis rod as shown in Figure `2 `or where desired, the strip 30 can be positioned around the front of the rod with the seat strip 28 extending under-the rod and around the back thereof, as inV Figure 4. s

j In order to further safe-guard the back ofthe occupant of the chair, straps 3I and 4I, of material similar to that used on the back and seat, are stretched between and securedto the side members 22 of thefback. These strapsvserve to sup- 45 port the back in the region of the kidneys and are l termed kidney straps. f

Thef glide of the seat is limited bymeans of loop members 32 fixed in any suitable manner ontheinner surfaces of the side rails around the rod I2, as shown in Figure 2. l

In order to protect the occupant from sun and rain, a canopy 33 formed on a suitable framework and covered by the same material asused for the seat and back is'provided and detachably 5 5 connected by wing nuts and bolts 34 orv any other suitable securing means to the upper ends of the side members 22 of the backof the chair. 3

A foot and leg rest formed ofr side members-35 and cross members 36 connected by a series lofytlo portion. Both the lcanopy and foot and leg rest are readily detachable and may be used when desired, the complete chair being clearly shownin Figure 1.

It may be readily seen that theY rod to which the cloths of the seat and back are attached is set back ofthe pivotal point or the pins 28 which connect the side members of the back and the side rails of the seatand the straps across the back.

cooperate with the positioning of pins 2O to pre# vent the back or spine of the occupant from coming in contact with this rod, thus providing a comfortable seat and back.

In the construction shown in Figure 4, the straps Ii and Il not only provide additional support for the occupants back but assist in preventing the back -from coming in direct contact with this rod. I

With the back pivoted at the point indicated by boltsior pini". `Il a smooth easy gliding back and Iseat is provided and which is self-adjusting by merely shifting of the occupants body. The

pressure of the front ends of the side'railsf on the upper l'ends ofthe brace membersA il hold the seat'in one cfa number of positions, the extent ofthe movement is controlled by the loop members 32,. The dotted line position showsthe 'extreme reclining position.` The chair may be'quicklyvfolded into afairly compact bundle for transportation or storage by tion,'what I claim as'new and'desire to secure by Letters Patent, is: 1

4. A folding chair .comprising connected leg frames, one at each side of the chair, each leg framehaving a front andl rear leg pivotally con'` nected at their upper ends, an arm rest pivotallyl connected with the legs in each frame, a prop pivoted to the arm and releasably supported on therear leg, bracingmeans between the front and rear leg, a back pivotally connected to each arm,

a seat pivoted at the rear to the lower end of the 40 back, means shiftably supporting the front of the seat on the leg frames.

5. A folding chair comprising connected ieg frames, one at each side of the chair, each leg frame having a front and a rear leg connected itv together near their upper ends, an arm rest pivotally connected to each 1eg` frame,y a back pivotally connected to said arm rests, a seat pivoted at the rear to the Vback adjacent to its lower end, meanssupporting the seat for back- 50 ward and forward movement with respect to the leg frames, bracing means for the legs of each leg frame to maintain the spaced relationl of thev front to the rear legs and movable props arranged between the back of the chair and the rear legs. i 55 6. A chair comprising connected ieg frames, one at each side of the chair, each'leg frame having foldable front and rear legs pivotally connected at the front of the chair, an arm rest pivotally connected to each leg yframe adJacent 60 to the top thereof, a back pivotally connected to said arm rests at the rear thereof, a seat pivoted at the rear to the back, means movably supporting the front of the seat in a manner to provide for adjustment of the seat and back ofthe chair ,05 to diiferent positions in use, a movable prop between the back and one leg frame when the chair is set up, and means 4for bracing the legs when the chair is set up, said pivotal connections and proportioning of the parts permitting the legs, 70 back and seat to be compactly folded upon movement of said prop from its back-supporting position. v
